title: Time-resolved fluorescent detection of Hg2+ in a complex environment by conjugating magnetic nanoparticles with a triple-helix molecular switch.
abstract: In this communication, we molecularly engineered a light-switching excimer oligonucleotide-based probe for time-resolved fluorescent detection of Hg(2+). By combining a time-resolved fluorescence technique and magnetic nanoparticles, Hg(2+) spiked in human urine was detected.
